Whatever people think how the “family Share” plan works, it is not how it will work. Obviously, MS NEVER share the details of exactly how the “Family Share” plan work, but instead just showing people the glossy cover. Until now.

…Anyone who you deem to be family had access to these games regardless of where they are in the world. There was never any catch to that, they didn’t have to share the same billing address or physical address it could be anyone. When your family member accesses any of your games, they’re placed into a special demo mode. This demo mode in most cases would be the full game with a 15-45 minute timer and in some cases an hour. This allowed the person to play the game, get familiar with it then make a purchase if they wanted to. When the time limit was up they would automatically be prompted to the Marketplace so that they may order it if liked the game. We were toying around with a limit on the number of times members could access the shared game (as to discourage gamers from simply beating the game by doing multiple playthroughs).
IF anyone think that “Family Share” plan can just let you buy 1 copy and 10 other people can simply play it for free is living in the lalaland. The family Shared plan is nothing more than a glorified DEMO.
Your game can share with 10 people, they can play it for between 15~60 mins at a time then you will pop out of the game into Xbox market place to prompt you to buy it. You only have a limited number of times to play it like this for the logical reason to prevent anyone from finish as game without ever buying it.
